    Same as when you had it... Just a new set of Wossners and a different cylinder head. As far as I know it is running with a single 44 SBN, Coffman half pipe and an SX pump.

  9. Re: Performance 650 Parts Coffman Exhaust Rad Flywheel 44mm SBN ADA

    Very good, but don't forget to subtract head gasket volume from the o-ring domes (1.1cc for 76mm bore). You are correct in that the end result is still 87 octane.
